PROBLEM TO BE SOLVED: To form an image of an excellent image quality on a recording medium. SOLUTION: This device is provided with a photoreceptor belt that the toner image is formed thereon, and an intermediate transfer belt on which the toner image is successively formed so as to overlap the other. Moreover, the color electrophotographic device is composed by equipping media transfer roller 7 being applied with voltage in polarity opposite to the toner for transferring the synthetic image on the paper sheet, the temp./humidity sensor 16 for detecting the temp./humidity of the device outside atmosphere, voltage information storing means 32 in which data of the application voltage on the media transfer roller 7 deduced from the printing condition and the temp./humidity of the device outside atmosphere, and a CPU 30 for applying the voltage of the value obtained from voltage information storing means 32 on the media transfer roller 7 based on the printing condition and the temp./humidity at right before executing the transfer of the composing image being detected by the temp./humidity sensor 16. |
